SANITARY SCREEN.

Application led September 25, 1913.

To all whom t may concern:

Be it known that I, FRANCIS GRANGER, a citizen of the United States, and a resident of Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Improvement in Sanitary Screens; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a screen for disseminating vapors of any desired character such as perfumes, disinfectants or antiseptics throughout a room or other apartment for the promotion of pleasing and sanitary or hygienic surroundings and condition.

rIhe invention has for its object the prolvision of a compact and convenient structure which may be readily hung for example adjacent heating apparatus or in any relation where the vapors may be most effectively and advantageously disseminated, by an open window, before an electric fan.

A further object is to provide means whereby a change in the character or kind of the vapors disseminated may be readily effected, or furthermore, where vapors of different kinds may be mingled and so disseminated.

With these objects in view the invention consists in a. construction and arrangement of parts one embodiment of which is illustrated in the accompanying drawing in which- Figure 1 is aperspective view of the complete screen and of means for suspending the samer; Fig. 2 is a vertical sectional view in a plane parallel with the face of the screen; Fig. 3 is a transverse vertical sec tional view on the line 3f-3 Fig. 1; Fig. 4 is a transverse horizontal sectional view on the line 4-4 Fig. 1; and Fig. 5 is a perspective view of one of the absorbent or screen members proper.

Referring to Fig. 1, the screen as a whole comprises a frame-work 1, preferably of hollow metal construction, the bottom and opposite sides of which may be rigid or integral with each other while the top or cap member 2 may be made preferably to fit over and inclose the ends of the side members as indicated in Figs. 2 and 3. The side members 3, 3, of the frame comprise vertical reservoirs 4, 4, and flanges 5, 5, which form slide or guideways 6, 6, for the reception of the absorbent or wick screen members. For improving Specification of Letters Patent.

the appearance of the screen as a whole and for protecting the absorbent or wick memw bers the opposite sides of the screen frame may be filled in with protecting wire gauzes, as 7, 7, thus forming an inclosed chamber S within the screen frame. The absorbing or wick screen members proper may consist of wire frames 9 of any suitable shape to conform to the shape of the frame and on these wire frames may be stretched the strands 10 of the wick proper by winding the same from end to end as clearly indicated in Fig. 5, and bringing the opposite ends together as at 11, said ends being extended as at 12 to provide the necessary capillary connection with the fluid receiving reservoirs 4, 4. The extremities 12 of the wick member may be weighted as at 13 to facilitate entering the same within the reservoirs and at the same time to insure that they extend well down into the volatile fluid.

In the use of the device the cap member 2 of the frame is removed and one or more of these wick frames 9 is inserted within the guide channel 6 of the main frame, while at the same time the extremities 12 of the wick are inserted in the reservoirs at either side of the frame. In the construction here illustrated I have shown a main frame adapted to receive two wick frames, but the number of frames may be increased as desired by properly modifying the construe tion of the main frame. In order that the cap 2 may not interfere with the capillary transmission of the fluid throughout the wick said cap does not contact with the wick but is spaced slightly away therefrom as shown in Fig. 2.

By employing a main frame adapted for the reception of several wick frames several useful results may be secured. In the first place the reservoirs 4, 4, on either side of the frame may contain volatile fluids of different characters, as for example one may contain oil of pine and the other a disinfectant, or one may contain a redolent or essential oil or fluid having the perfume of a certain fiower, and the other a fiuid having a different perfume. If it is desired to disseminate the vapor from one of these fluids at a time the wick frame may be inserted with its wick terminal 12 extending into the reservoir 4 containing that fluid. If it is desired to Change the character of the vapor disseminated it is only necessary to withdraw the wick frame and insert another with the wick terminal of the latter extending into the opposite reservoir containingl the fluid of different character. Therefore by a mere change of the wick sci'een or frame the character of the vapor as disseminated may be quickly changed. If, onl the other hand, it is desired to combine two or more vapors, the wick terminal of one of the wick frames insertedvin the main frame may extend into one of the reservoirs and that of the other into the other reservoir, said reservoirs ccntaining different kinds of volatile fluid. If, furthermore, it is desired to produce an excessively pungent vapor of one kind the reservoirs on each side of the main f ame may contain the saine kind of fl'uid and the .vick

terminals of the two wick frames when in-V serted in the respective reservoirs will feed this fluid to both wicks.

TWith the one or several wick frames properly positioned within the main frame the screen may be suspended in a window of the room and the air as it enters the room will disseminate the vapors throughout the room. On the other hand, the screen may Vbe mounted in front of an electric fan and prefe ably on the safety guard of the fan itself. To this end l may provide a suitable form of supporting frame for the screen such as that illustrated in l? ig. 1, wherein such frame comprises side members 14, 14, having. the hooks 15 for embracing the side members 3 ofthe screen frame, a bottom member consisting of a supporting loop 16 adapted to embrace the bottom member of the screen frame. The side members may be extended as at 17, 17, to form fastening shanks of any desired construction which may be attached' Cop'es of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents odor of the pine possesses well known soporific qualities. The device will also be found useful in theaters and public halls for disseminating purifying or disinfecting vapors,

It is to be understood that the screen may be made of various sizes to suit differing conditions, and may be constructed to contain one or a plurality of wick frames or screens as occasion may require.

Other changes and variations may be made in the structure and arrangement of the apparatus within the scope of the appended claims.V Y

What l claim is l 1. 1n a vaporizer, the combination with a supporting frame having hollow side meinbers forming fluid reservoirs', and having guide-ways, a wick frame having absorbent material stretched thereover, said frame being adapted to be placed in said guide-ways with `a portion of said absorbent material extending into. one' of said reservoirs.

Q.V ln a vaporizer, the combination with a l supporting frame comprising side and bottom members, saidside members being hollow to forni fluid reservoirs and having guide-ways formed thereon, a wick frame adapted to fit within said guide-'ways and carrying' a wick member adapted to extend into one of said reservoirs and a cap member for said frame adapted to in close said reservoirs and confine said wick frame within said main frame. s

3. A vaporizer, comprising a supporting frame havinghollow side members forming separate fluid reservoirs, a plurality of interchangeable separate wick frames carrying wicks the terminals of which are adapted to extend into said reservoirs, means for holding said wick frames in said supporting f ame in operative connection with said reservoirs.

In testimony whereof, I the said FRANCIS GRANGER have hereunto set my hand.
